This loop is all singletrack. Start on Warm Springs Trail #103. The trail climbs gradually on good singletrack with some rocky sections. Watch for wild raspberries where the trail crosses scree fields.

After a mile is the first junction. Go right and cross the creek.

The next junction is well marked, go left on Porcupine Creek Trail #205 to Twogood Cabin. Here the rocky sections end and the trail is good singletrack with gravelly sections.

Not too far beyond Twogood Cabin starts the serious climbing, gaining close to 2000' in about 2 miles. There are many switchbacks and most are ridable is you can keep your balance and power.

Porcupine Creek Trail meets Warm Springs Ridge Trail #177, go hard left. The trail stays near the top of the ridge rolling up and down for the next 3 miles where you come to an old hunting camp.

Here the trail seems to deadend. Turn around and you will notice a faint trail taking off to the left and back toward the ridge. The descending starts soon after this.

After the first section of descending, and 4 big switchbacks in the woods, the trail bottoms out and climbs briefly. Look for a sign for the Fire Creek Trail #404 on a tree on the left.

Fire Creek Trail is never too steep but has many switchbacks. This is a super fun descent.

Try to ride this early in the day before the lightning rakes the highcountry ridges.
